In an operation wherein a gaseous stream, such as an air stream, is contacted with a liquid selective solvent for a component of the gaseous stream for the removal of said component from the gaseous stream, improved results are obtained, particularly in a direct gas-liquid countercurrent contacting operation, by employing a liquid selective solvent which has a viscosity of less than 35 mPa s at 25.degree.C. Suitable such solvents include diethyl phthalate, dioctyl phthalate, dioctyl adipate, acetyltributyl citrate and diisohexyl phthalate, particularly blends or mixtures thereof.
